These drug companies keep track of how many and what prescriptions these doctors write and pay the doctors handsomely, sometimes its secret, under the table payments or fancy dinners and trips for their family to Europe. Ski trips to Aspen, luxury box seats at NFL football games, etc etc.... All for prescribing more drugs to more unsuspecting people. Im not sure how much big pharma makes on statins, but its somewhere around 50 billion + a year if irc. Its a huge f****ing scam
